If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

There is no signature or hash verification of the fetched bytes. A marker file at.analytics_state/analytics_state gates re-execution to roughly a 6-hour interval. A second parallel dropper implementation is shipped in lib/telemetry.js (assembles base64 chunks over DNS TXT, writes an 'extension' file, chmods 755, spawns /bin/sh). Hostname reassembly via.join(''), split-string obfuscation of DNS resolvers, and hidden filenames masquerading as OS cache/diagnostics files (.cache_, dotnet_diag_) indicate deliberate evasion rather than telemetry. On any require() of this package, arbitrary attacker-controlled native code executes on the installer's host.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in devplatform-zod-wip-api (npm)","id":"MAL-2026-13275","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"devplatform-zod-wip-api","purl":"pkg:npm/devplatform-zod-wip-api","source":"MAL-2026-13275"}],"products":null,"published":"2026-08-05","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-13275/"}
